  • Next message: Bob Christy: "STS-134"

    Thank you to all who responded on and off-list to my recent request for additional comment on policy options for
    reporting high resolution ground-based imagery of Earth satellites. I believe that there is general agreement in favour
    of Option 2, with the requirement that raw frames be made available.
    
    Option 2 is described here: http://satobs.org/seesat/Aug-2010/0134.html
    
    The proposed draft rules, as appended to this message, are based on those in the above message, with some changes,
    especially to the raw frames requirements. I am open to suggestions for improvement in content and clarity. I have very
    little technical knowledge of this field, so I am especially interested in suggestions for improvement from imagers.
    
    PLEASE NOTE: The final rules that result from this consultation will be retroactive to the present time: 2011 May 16,
    11:36 UTC.

    Draft rules for reporting high resolution ground-based imagery of Earth satellites
    
    SeeSat-L welcomes the reporting of high resolution ground-based imagery of Earth satellites, subject to the following
    required supporting information:
    
    ID of object: COSPAR, USSTRATCOM catalogue number, common name
    
    Description and dimensions of object (metres), if known.
    
    Observing site location: latitude, longitude, altitude, to nearest 100 m
    
    Date/time of obs: UTC. For single frames, report time to nearest second. For video, report start time and duration to
    nearest second.
    
    Range to object: km
    
    Telescope: make/model/aperture
    
    Camera: make/model
    
    Tracking method: hand-guided, or mechanical (make/model)
    
    Data acquired: total duration, frame rate, exposure per frame, resolution & bit depth of raw data
    
    Processing: describe the process of frame-selection and/or image-processing used to obtain reported results.
    
    Raw image frames: Results consisting of one or more frames selected from a longer series of frames, whether
    image-processed or not, must be supported by at least 60 seconds of the complete set of raw frames centred on the time
    of the results, i.e. 30 s before and after. By raw frames is meant the data exactly as taken from the camera that formed
    the input into the process of frame-selection and/or image-processing that produced the result. If the result is
    displayed on a web site, then a link to the raw data should be located in close proximity. An alternative would be to
    place a statement that the data is available upon request, in close proximity to the results.
